UNITED STATES JOHN F. APPLEBY, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TO THE MINNEAPOLIS HARVESTER WORKS, OF SAME PLACE.

GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 275,114, dated April 3, 1883.

Application filed SeptemberdlSBi. (Model) and useful Improvements in Grain-Binders;

and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this application.

My invention relates to that type of automatic grain-binders in which the grain discharged from the upper end of the elevator is packed into a gavel of the proper size and degree of compactness, and in which the binder devices proper are automatically setiu motion whenever the gavel is in the proper condition to be bound up; and my invention consistsiu certain novel features ofconstruction and modes ot'operatiou of parts more especially adapted to this type of grain-binder, as will be hereinafter more fully explained, and as will be particularly pointed out in the claims of this specification.

Toenable those skilled in the art to understand and practice my invention, I will now proceed to more fully explain the several features thereof, referring by letters to the accompanying drawings, forming a part of this specification, and in which I have shown so much of a grainbinder as seems to be necessary for the purpose of illustrating the several features of my invention, the machine being of the form known as the Appleby binder.

In the drawings, Figure 1 is a partial side view of a binder embracing my invention, and viewed from in front of the harvester, to which the binder may be attached. Fig. 2 is a view of the opposite side of the binder. Fig.3 is a top view. Fig. 4 is a partial vertical section at the line on w of Fig. 5. Fig. 5 is a cross-section at the line y y of Fig. 4. Fig.6 shows in face view and in cross-section a cam-plate, to be hereinafter described. Fig. 7 is a partial sectional view, taken at z a, Fig. 3, looking in the direction indicated by the arrow at Fig. 3. Fig. 8 is a view of the same side of the machine shown at Fig. 1, but with. the moving parts in a 'difl'ereut relative position. Fig. 9 is a detail view of one of the gears detached, to better show a circular ledge or rib on one side thereof, that will be hereinafter more particularly described.

In the several figures of the drawings the same part will be found designated by the same letter of reference.

A B C, Fig. 3, are the three upright, and D E the two horizontal pieces composing the main frame of the binder, which, as usual in the mounting of binders of the form shown, is attached to the harvester in an oblique position, and so that the binder will properly receive into its gavel-receptacle the grain discharged from the upper end of the elevator.

F is the main casting, having the two parallel pipes to I), the lower one, a, of which is securely bolted to the binder-frame and carrying the main gears GH and other parts, such as the cam-and-rack wheel, the kuotter, cordholder, &c., used in the Applebykiud ofbinder, and not shown in the drawings.

I is the usual shaft, on which are mounted (with other parts not shown) the sheaf-discharging arms cc,- andJ is the shaft on which is mounted the needle-arm d.

K is the shaft, which, by means of its cranks e 0, drives the packersff, and on which are mounted axially the pinion g, (which drives the binder devices proper,) and also a planetary system of gearing, (to be presently described,) the said binder devices proper deriving their motions from said pinion 9 through the medium of gears G H.

The planetary system of gears consists of a spur-pinion, a, (see Figs. 4 and 5,) made fast to the inner face of the platej, two pinions, b 0 mounted loosely on studs e,which are each made fast at one end to a cross head or bar, t'*, that is keyed fast on the shaft K, and an internal rim-gear, g, the hub of which is either integral with orfast to the hub of pinion g, that drives the large gear-wheel G. Thelower ends of the packiug-armsff are connected by pivoted rods or links it h to the pintle i,which is mounted in the hub or lower end of an arm, L, which projects downward and backward from the pipe to, as shown. 1

M is the compressor-arm, or the arm against which the needle-arm forces the gavel during the banding'cord may be readily tied round IOO about it, said arm being arranged and operating so that at certain times, or under certain circumstances during the binding operation, it will yield to the pressure of the gavel, and so that it will also swing clear down (out of the way) whenever a sheaf has to be discharged from the machine, all as will be hereinafter explained.

N is a drive-shaft mounted suitably in the harvester-frame, and carrying a chain-wheel, O, which, through the medium of a chain-belt, 1, imparts the necessary motive power to the binder, about as usual. This beltP, as shown, engages with a chain-wheel, Q, on the packershaft K, said wheel being fast on the hublike portion 7' of the face-platej. (See particularly Figs. 3 and 4.)

R is the crank of the needle-arm shaft, driven through the medium of the pitman S from the gear G. On the inner side of this gear is a circular rib, 70, (see Fig. 9,) which periodically comes against and holds downward the upper end of the arm lof rock-shaft 'l, for a purpose to be presently explained.

m is a rod pivoted to arm I, and carrying a spiral spring, a, which serves to pull in one direction on the arm I, as shown, said spring being confined endwise between the nnto and the stand orlugp, that projects from the main casting. On the outer side of gear G are a projecting cam-like device, q, a pivoted arm, and a spring push-bar, s, the functions and effects of which will be presently explained.

U is a camplate, which is fasten the end of the packer-shaft K, and which controls the action, to a certain extent, of thc chockingarm 25, that is pivoted at its upper end to the stand a, (bolted to frame-piece A, as shown,) and that carries at its lowerend an anti-friction roller that works in the groove of camplate U. Said arm t has a projecting lug, a", on its inner side, through which passes a rod, n, that is pivoted at one end, as shown, to the stand a, and which carries on it a spiral spring, '10, confined endwise between the said ing of arm 15 and the nut 00 on the threaded end ofsaid rod 42, the operation of these combined devices being such that the spring 20 acts constantly with a tendency to move the lower end of arm t, in the direction indicated by the arrow 20 at Fig. 8.

a Figs. 2 and 3, is a sort of dog or anglelever mounted to turn freely on the shaft J, and having at one end a laterally-projecting lug, N, Fig. 7, that underlies the back side of the needle-arm, (near its heel,) and the other end of which is connected by a short pitman or link, 0 to the compressor M, as shown, which latter has a projecting portion, (1*, beneath that works against the upper end of the spring push-bar 0 This push-bar is arranged within a cast frame, f that projects obliquely down from the end of pipe-casting a. It has cut on it a screw-thread, and is provided with two nuts, between one of which, and the bottom of frame f the spiral spring 7L2 is confined endwise, the other nut, 5?, acting to hold the push-rod in its frame against the tendency ofspring h to move it in the direction indicated by arrow at. Fig. 1. here the projection of the compressor M bears on the pushbar 0 the latter is provided, as shown, with an anti-friction roller, 0.

I? is a curved arm made fast to the end of rock-shaft T, and formed with laterally-projectingspurs 1 and 2, between which lies the pushbar 6 and by which the upper portion of said push-bar is raised and lowered by the rocking (in one direction and theother) of the shaft T. The castingf is bifurcated at its upper end, and bar 0 is loosely connected at the opposite end, to permit of the described motion.

With what has so far been said, together with the drawings, the following additional explanations will make clear the operations of the various parts of the machine shown and hereinbefore alluded to.

The wheel 0 being continuously driven by the shaft N of the harvester, the chain-belt P (passing from said wheel to the chain-wheel Q) keeps wheel Q constantly rotating, and the inclosed spur-pinion a, being fast to the hubj must of course likewise constantly rotate, and said pinion will by its rotation effect the driving of either the packer-shaft or the binding mechanism proper, or both, according to circumstances. The spur-gear a engages with and drives the two gears b and c and these gears, since they engage with the internal rimgear, 9 and have their journals 6 fast in the cross-head, must operate to produce either the driving of gear g, or else the driving of shaft K, in the same direction of rotation as butat aless speed than the geara travels. Now,supposethe gear G and pinion g to be chockcd or prevented from turning, so that internal gear g is held stationary, and it will be seen that as the gear a (and the parts jj fast therewith) are rotated bythe action of belt P on wheel Q the gears b and 0* will travel around in engagement with the now stationary gear 9*, and that their studs 6 will carry around the cross-head i, to which said studs are fast, which latter is fast on shaft K,thusrotatingsaid shat'tand efi'ectingthrough the cranks e of said shaft the proper movements alternately of the packers ff, which packers, it will be seen, have an extent of motion (unlike those heretofore used in the Appleby machine) sufficient to enable them to reach clear back of the needle-arm and its guard, and thus more efl'ectually gather and carry forward and downward the grain to be packed into the gavel-receptacle.

IIO

The gears G and g (and consequently the binder mechanism proper) are prevented from turning,while a gavel is being collected, in the following manner: The arm 1" presses upward against the lower end of the chocking-srm t (or, a

rather, against the anti-friction roller 15 at the lower end ofsaid arm) in a direction almost dead against the center of vibration of said arm 1, and the strength of the spring to is sut'ficient to prevent the arm t, pressed against in this manner by arm r, from moving; and hence the gear G is, so to speak, chocked. Of course this prevents the gear 9 from turning, and the consequence is the driving of the packer-shaft, as just hereinbefore explained. The arm while it cannot possibly move in a direction that might permit it to drop out of contact at its upper end (see Fig. 8) with the roller F, is yet capable, under extraordinary strain, of moving in an opposite direction against the spring push -bar 8, for a purpose to be presently explained. \Vhenever thepaekers,or either one of them, shall meet with that degree of resistance which is due to the collection within the gavelreceptacle of the requisite amount of grain properly compacted to form a sheath with, then the gear g will become released (or unchecked) and the gear 9 will rotate and drive, through the medium of gear G, the binder devices, because the cam-plate, fast on the end of packer-shaft, having come to a position to permit the unlocking of said gear g, and it now requiring less power to move the binder devices than to continue operating the packers, the mechanism for driving both of the sets of devices will naturally operate that one which will move the more easily. This unchoeking of the gear G and the consequent movement of the binder devices can, however, occur at only one of two points or periods in the rotation of the packer-shaftviz., when one or the other of the opposite depressed portions, 4 and 5, (see Figs. 6 and 8,) of cam U gets into such a relative position with the roller i as to permit the arm t to be forced back and down by the pushing or toggle-like action of the upper end of arm 2", which then can pass (upward) by the said roller t and the two points or times at which alone the binder devices can be started into motion are those at which one or the other of the packers has just descended to'a point such that the needle-arm will start in immediately in its wake, and so catch and compress the last entered stalks of grain. The force exerted by the spring 20 to hold the chocking-arm t up to its work may be regulated by turning in one direction or the other the nut a", so that the nnchockiug alluded to will not occur until a given predetermined resistance is offered to the-packing movement of the packers. The gear G, being nowin motion,is driven one complete turn or revolution, and thereby the needle-arm,-tyer, 850., are operated in a manner nearly the same as usual, and the gavel collected is bound into a sheaf and discharged from the machine. fairly started the packers stop, because the spring chocking-arm is then thrown outward into one of the enlargements or extensions 6 7 of the cam-plate U, and the roller t coming against the shoulder-like portion of such part 6 or 7 the cam-plate itse1f(which is fast on the end of packer-shaft) is now chocked, and will remain so during an entire rotation of wheel G. The cam U will remain during this rotation of When the gear Gr gets the wheel Gin the position shown in Fig. 1,.

which will carry the roller t across, the path of the cam q, so as to be operated thereby, as will be hereinafter explained. The size of gear G is such and the relations of the parts such that during the one revolution of said gear the needlearm will have made one forward and one backward stroke, and these strokes are unlike, as will be presently explained, for a certain purpose. As I have just said, the packer-shaft is locked against turning by the roller t of the checking-arm t catching against one of the shoulders of portions 6 or 7 of cam-plate U. Now, as the gear G is about completing its revolution, and just before it becomes rechocked,

the cam-plate is released from the checking action of roller t and the packer-shaft left free to'be turned, in the following manner: The inclined or cam-like ledge or lateral projection g on wheel G comes into contactwith and pushes back the lower end of arm t, so as to unlock the cam-plate; but, having accomplished this,

the roller t ,which can be thus forced back only far enough to bring it into contact with the circular or concentric part of the inner wall of the groove (in U) in which it works, operates then to again chock the gear G by contact with the end of pushing-arm 1', as before explained.

It will be observed that there will be an instant of time when both gear G and the packer-shaft might move; but it is deemed necessary to have the construction of cam U such as to permit this, because it is deemed best to allow a little time within which to effect the stoppage of one set of devices and the starting up of the other, and vice versa. Even, with this provision, and with the best possible detail construction of the bindermachine, there may be a possible contingency of the two sets of devices, driven by the system of driving de-; vices shown, getting into a dead lock, in which possible (though remote) contingency some breakage or derangement of some part would occur. To avoid any injury from any such contingency l have made the arm 1' capable of a movement to get out-of the way, (as before al luded to,) as follows: In case of any dead lock,

,and hence extraordinary strain between the npper end of arm 0* and roller t the former will .be wedged or forced backward against the push-bar s and get past the roller t 7 Of course for the purpose of driving either the shaft K (to move thepackers) or the gear G (to operate the binding devices-proper) the particular construction of gears and devices shown need not be employed, as other arrangethe two devices to be driven according as one LII 13o ing main driver to either one or the other of or the other offers more or less resistance than the other to the driver, and a supplemental feature of novelty in the contrivance shown being the use, in connection with some such means as just alluded to, of means for automatically checking or holding still each or either of the devices to be thus driven while the other is in motion or action.

Although the shaft carrying the needle-arm is rocked by a simple crank, R, and the pitman S, connecting said crank to the wrist-pin 8 (see Fig. 8) of the gear-wheel G, I have so combined and arranged the parts, it will be seen,

' that the slowest movement and greatest power of the needle-arm are developed during the forward stroke of the latter, (while it is compressing the gavel and binding it into a sheaf) and the quickest movement and least expendi ture of power occur during the backward stroke of the needle-arm when it has no work to do.

It will be seen that the gear Gr makes about two-thirds of a revolution during the binding or forward movement of the needle and only about one-third of a turn during the back stroke of the needle. By this arrangement I not only effect a very economical application of the power necessary to the binding, but'I also effect avery long slow movementof the forward end of the needle-arm at the time the tying operation occurs, thus comparali vely holding the gavel in a compressed condition longer by the needle-arm, and greatly relieving the tying mechanism of the difficulty ofoperating against that strain of the bundle on the string exerted in machines as heretofore constructed with simple crank devices to operate the needle-arm shaft. During the packing and binding of the gavel between the needle-arm and packers on one side and the opposing compressor-arm M on the other side the latter remains perfectly rigid, (while the packers are at work,) but becomes yielding or elastic in opposition to the action of the needle-arm, and after the binding of the sheaf shall have been effected said arm M is permitted to swing clear down and out of the way to permit the free discharge of the bound sheaf. 'lhese qualities of the arm M are due to this operation of the parts-via, during the operation ofthe packers and while. the needle-arm is at rest in its-rearmost position, as shown at Fig. 7, the projection If of-v the dog a (see Fig. 2) is held down by the heel portion of the needle-arm, and thus the dog a is made through the rigid connecting-link c to hold up securely the pivoted arm M; but as soon as the needle-arm begins to move forward, and while in the position shown in dotted lines at Fig. 7, the arm M is relieved from this influence of the-needle-arm d on lug b and the arm M is then supported or kept in the position shown by the roller 6 of the push-bar 0 which latter, being ayielding bar, permits the arm M to be forced downward to a limited extent, as indicated by the dotted lines at Fig. 7. The capacity of the arm M to thus yield to-theaction of the'gavel, being compressed more or less, is regulated by adjusting the nut on rod 0 that makes the spring more or less yielding. When the bundle shall have been bound and is ready to be discharged the usual sheaf-discharging arms a c sweep it downward, the arm M being forced clear down out of the way of the sheaf as it makes its exit. This, however, could not occur were the supporting-roller to maintain the position seen at Fig. 7, but just prior to the depressing action caused by the outgoing sheaf, or at the same time, the upper end of push-bare is thrown down, so as to bring the roller 0 into the position seen in dotted lines at Fig. 7. This movement of this end of bar 0 is effected by the bifurcated end of arm l of rock-shaft '1, which latter is at the proper time turned (in the right direction) by the action ofledge k on its arm l. of the sheaf the arm M is positively returned to its original position by the action of the heel of the needle-arm on the lug b of dog a and thereafter the rock-shaft T, having had its arm lreleased from the action of ledge k,

is rocked back by the power of the spring a in the pull-rod m. (See Fig. 8.)

Without wishing to be understood as restricting my claims of invention to any pre cise forms or proportions of parts, or to any particular devices not essential to the principle of construction and mode of operation of the improvements made by me, what I claim as new, and desire to secure by Letters Pat ent, is-- 1. In combination with the packing mechanism or devices and the binder mechanism of a grain-binding machine, means for imparting the requisite power and motion to both of said mechanisms andoperating to drive that one which requires the least power, substantially as set forth.

2. In combination with the binder mechanism, the packing mechanism, and means for driving both of said mechanisms, suitable means for holding in arrest the action of each of said mechanisms whenever it shall have ceased its action and the other one shall have started to work, substantially as set forth.

3. In combination with the packer drivingshaft and a device for driving the binder mechanism, a driving mechanism capable of driving either the packer-shaft or the device 'for actuating the binder mechanism, and" always in operative connection with both, substantially as set forth.

at. In combination with the binder mechanism the packer mechanism, and a driving mechanism capable of driving either one or the other or both of the first-named two mechanisms, means for looking or holding in inaction each of the driven mechanisms, which looking or holding means is thrown into cooperation with each of said driven mechanisms by a device connected with the binde mechanism.

5. In combination with the'crank of the After the disch arge' IIO needle-arm shaft and the gear-wheel from which said crank is operated, a pitman connecting the said wheel and crank in a manner to cause the binding movement of the needlearm to be much slower than its return movement, as set forth.

6. In combination with the compressor-arm M, means by which said arm is rendered rigid during the compacting of the gavel by the packers and yielding during the subsequent compression of the gavel between said arm and the needle-arm, as set forth.

7. In combination with the needle-arm, a compressor or resistant, M, and means for locking the latter to the former to hold the latter rigidly against the action of the grain while being packed into the gavel-receptacle.

8. In combination with the arm M, a spring push-bar for holding said arm up against the action of the needle-arm in the compression of 20 the gavel, as set forth.

9. In combination with the arm M and a yielding device for supporting it, means for releasing said arm from its support, substantially as and for the purpose set forth.

10. A mechanism for driving the two sets of devices that alternately operate to gavel and bind the grain, which is capable of being driven from a single drive device, and which operates to drive either oneor both of the said two sets of devices, as set forth.

In witness whereof I have hereunto set my hand this 11th day of July, 1882.
